They don't hire well at all. You look at who is on their research team and it's people with social science PHDs, not computer science. Looking at the state of the site it's not a surprise. Highly incompetent people have taken over for a while. Let's not forget a member of the original executive team was a sex pest too.

For like 10 years the only feature development they did was by stealing ideas from GitLab. I wouldn't be shocked if little if none engineering discipline has took place at all during this time if it's this brittle to frequent change.

Guessing it was mostly held together with duct tape and poorly written tests/monitoring systems if any other corporate driven software.

We're really going to find out over the next few years which businesses have good practices or not.
